The present invention relates to a cassette-type cleaner for cleaning the head drum of a video signal recording and reproducing apparatus, and more particularly, to a head drum cleaner of a video signal reproducing apparatus which can be extruded and used when necessary by embedding a washing liquid.

Video Tape Recorder (VTR) is a device that converts video signals into magnetic signals and records or plays them. Recently, due to the development of related technologies and various uses, they are widely used and widely used by the general public. Accordingly, the use and handling of video signal recording and reproducing devices are becoming important. In particular, the most important recording and playback functions of the video signal recording and reproducing apparatus are performed through the head. When foreign matter gets stuck or moisture gets in the head, it not only affects the screen but also affects the instrument itself. There is work.

Therefore, it is often necessary to clean the head drum, where the head drum of the video signal recording and reproducing apparatus is deeply installed inside, and it is difficult to clean the head drum, and the head drum itself is rotated so that the entire surface of the head drum is It was very hard to clean.

On the other hand, in order to eliminate the above problems, there was a device in which a cassette-type head drum cleaner was developed to wipe the head drum of the video signal recording and reproducing apparatus, but in the conventional case, a hole was formed in the case side of the cassette. Since the cleaning solution is injected into the cleaning tape through the hole, it is cumbersome to inject the cleaning solution every time, and there is a risk of loss because the cassette and the cleaning solution container must be stored separately. There was this.

Therefore, the present invention, by installing the cleaning solution container in the cassette in order to remove the above-mentioned defects, by forming a pressing portion in the cleaning solution container exposed to the outside and the inlet is installed in the place where can be seen through the window of the upper case, It is an object of the present invention to provide a head drum cleaner of an image signal recording and reproducing apparatus that can be used not only to eliminate the drawbacks of storing the cleaning liquid container but also to use it in a convenient way.

Hereinafter, the configuration and operation effects of the present invention will be described in detail with reference to the illustrated drawings.

The present invention provides an upper case 2 having a window 1, a lower case 3 into which each component is inserted, a supply reel 5 and a reel 6 wound around a cleaning tape 4, and a washing liquid container. It consists of (7), the upper case (2) and the lower case (3) is formed with a pressing hole (8) at the bottom, the coupling groove (9) in the inner ribs, respectively, the washing liquid container (7) Forming the engaging projection 10 on the side to be fixed and coupled with the coupling groove (9), to form the injection hole 11 of the thin hole so as to be adjacent to the cleaning tape (7) of the supply reel (5), It has a structure in which a pressing portion 12 having elasticity is formed in the lower portion so as to be exposed through the pressing hole (8).

Reference numeral 13 is an upper plate, 14 is a lower plate, and 15 is a hole.

The present invention having the structure as described above can be injected to the cleaning tape (7) by a simple method by pressing the pressing unit 12 to inject the cleaning liquid through the injection port 11 of the cleaning liquid container (7) In addition, the injection port 11 of the washing solution container 7 was installed under the window 1 of the upper case 2 so that the scanning state of the washing solution could be observed.

1 is a perspective view of the present invention, the upper case 2 and the lower case 3, the appearance and assembly of the supply reel (5), the winding reel (6) and the cleaning liquid container (7) wound around the cleaning tape (4) The method shows that the upper case (2) forms a window (1) to observe the state of injection of the washing liquid inside, and the supply reel (5) and the reel (6) are respectively the upper plate (13). And the lower plate 14 is installed, but the upper plate 13 of the supply reel 5 is separated, and the coupling protrusion 10 of the washing solution container 7 is coupled to the coupling groove 9 of the lower case 3 and then the upper plate ( 13), the upper case 2 is covered, but the pressing portion 12 of the washing liquid container 7 is exposed to the outside through the pressing hole (8).

2 is a combined perspective view of the present invention, the upper case 2 is shown as an imaginary line, and the upper plate 13 of the supply reel 5 is shown in a partially cut state, respectively. 12 is applied to the cleaning tape 4 wound on the supply reel 5 through the injection port 11 of the cleaning liquid container 7 by pressure, and when the applied force is removed, the pressing portion 12 ) Is returned to its original state, and the scanning state is observed through the window 1 of the upper case 2, so that the washing solution can be properly injected.

As described above, when the head drum cleaner is mounted on the video signal recording and reproducing apparatus while the cleaning solution is injected, the cleaning tape 4 is wiped by wrapping the head drum. At this time, dust or dirt is removed from the cleaning tape (4) with the cleaning liquid on it. It works to wipe things off.

On the other hand, Figure 3 is a combined state of the conventional head drum cleaner to inject the washing liquid from the outside using a separate washing liquid container, for this, the lower case (3) has formed a hole for injection 15 in the side, supply The reel 5 and the reel 6 have a large diameter so that the injection port of the washing liquid container can be easily reached.

However, the present invention reduces the size of the supply reel (5) and the reel (6), and by removing the problem of storing the washing liquid container (7) separately by installing the washing liquid container (7) in the interior space, It is possible to record and play back a cleaner and clearer video signal by allowing the cleaning solution to be injected and used by the method.

Claims (1)

The upper case 2 with the window 1 formed therein, the lower case 3 into which each component is loaded, the supply reel 5 with the cleaning tape 4 wound, the winding reel 6 and the cleaning liquid container 7 In the configured head drum cleaner, the pressing hole 8 is formed in each side of the upper case 2 and the lower case 3, and the coupling grooves 9 are formed in the inner ribs, respectively. The injection hole of the hole formed so as to be adjacent to the cleaning tape (4) of the supply reel (5) on the upper side of the washing liquid container (7) to form a coupling protrusion 10 to be fixed to the coupling groove (9) A head drum cleaner of a video signal recording and reproducing apparatus, characterized in that (11) is formed, and a pressing portion (12) having elasticity is formed under the washing liquid container (7) so as to be exposed through the pressing hole (8).
